To all whom it may concern:

. Be itknown that I, JAMES G. WILSON, a

citizen of the United States, residing at Coalwood, in the county of McDowell, State of West Virginia, have invented certain new and useful Improvements in R0- tary Engines; and I do hereby decl'are'the following to be a full, clear, scription of the invention, such as will en'- able others skilled in the art to which it appertains to make and use the same.

This invention relates to certain novel and usefulimprovements in rotary engines.

In carrying out my invention, it is my purpose to provide a simple, powerful engine which may be operated at a relatively low cost to develop its maximum e-fii'ciency.

Still a further object of my invention is the provision of an engine having the parts thereof so correlated and arranged that the liability of motive fluid leaking or escaping is obviated, inasmuch as I have provided a novel method of arranging and assembling the packing to avoid this disadvantage.

ll also aim to provide an engine which will run easily and positively and which will not be liable to injury or accidents which would require frequent repairs.

With the above recited objects and others of a similar nature in view, my invention consists in the construction, combination and arrangement of parts falling within the scope of the appended claims.

In the accompanying drawings, like charactersof reference indicate like parts in all the views, and Figure 1 is aside elevation with one of the plat es removed. Fig. 2 is a sectional view. Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1. Fig.

section of one of the pistons.

-' 1 Referring now to the accompanying drawings in detail, the numeral 1 designates the bed plate of my engine which carries the ring-like casing or stator A. The numerals 2 2designate the supportingstandards carrying the shaft 3 upon which is mounted the revolving member or rotor B. This rotor and exact decompact and Fig. 5' is a cross sectional view taken on the line 5-5 of Fig. '1. Figs. 6.

end a tongue co nprises the hub section 4 carrying the disks 5-5, the entire rotor having the general appearance of a spool and is provlded with a series ofradially extending sockets or grooves 6 in which slide the piston heads or blocks 7, each piston having a guide rod 8 around which 1s coiled a tension spring -9, while the wearing edge-ofeach piston is provided with an anti-friction roller hearing 10. It will be evident that the pistons are normally forced outward by the springs thereof in the well known manner employed in this class of engines, and are designed at predetermined times in the revolution of the rotor to be forced inward of their sockets by contact with the eccentric walls or cam surfaces of the stator. The inner faces of the disks 5- -5 adjacent to the peripheries thereof ride against the side flanges 1111 of the ring casing or stator, as will be clearly seen by reference to Figs; 1 and. .2.

The inner circular wall of the stator is indicated as an entirety by the numeral 12, and is of less width than the cross distance between the two disks 55 so that.

of this stator. This inner wall 12 of the stator is formed with the segmental section 14. The motive fluid inlet is shown at 15, thus penetrating through the wall of the statgsr, the opening of the port being shown at 1 i The numeral 17 designates a channel com- -muni.cating with the circumferential channel 18 extending through the wall of the communicates with 'the interior of the stator, as will be clearly seen by reference to Figs. 1 and 2. The outlet port is shown 3 sections 23. Likewise the edges of the circular wall between the port 19 and the outlet 20 are formed with notches or recesses 24 I for the reception of the teeth or projections 25 of the eccentric packing ring section26. Each packing ring section 23 carries at one 24 adapted to fit in the notch 25 in the abutting end of the companion ring section 26, while at its opposite end each ring section 23 has a notch 27 for the shoulders 13-13 are formed at each side.

stator and terminating in the port 19 which '23 taken with the section 26 make up a complete packing ring and that I employ two of such rings, one at each side of the stator. To further effectively pack the en'- -gine, I make use of packing plates each formed of two sections.

Figs. 8 and 9, it will be seen that these packing plates which I have designated as an entlrety by the numeral 32 have the two sec- 7 tions thereof jointed by the tongue and "ing my improved readily apparent.

groove connections 33,-.while 34. are short springs between the two sections and nor mally tending to force them apart. These packing plates'lie across the notched portions 29 of the packing ring sections and are normally pressed inward toward the center of the engine by the springs 34.

. From the above description taken inconnection withthe accompanying drawings, the construction and the mannerof cm by rotary engine wil be Referrlng now to Figs. 1 and 2,-i t will be seen that as the motive fluid enters through the conduit and the ports 16 to the interior of the casing, it operates on the pistons which are extended and ride in the space between the ports 16 and 17 until the port 17 is reached, where such fluid enters the channel 18, the pistons no-w striking the graduallywidening eccentricv surfaces of the interior wall of'the stator and (of the packing ring thereat, so that such pistons are pushed inward until they reach the port 19 when they are again forced outward by thespring and are subjected to the motive fluid coming through the port 19, until they pass the upper port 20.- Between the outward and in- .let' ports thepistons again ride over the cam Byreference to I compact;efiicient type of engine of this general class, and while I have herein shown and described one particular embodiment of my invention, I wish it to be understood that "I do not limit myself to all the precise details of construction herein set forth, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the claims.

VVha-t I claim is:

1. The combination with a ring-like stator having the interior wall thereof formed with cam surfaces and notches in the edges of said walls, of an inlet port and an outlet port for the stator, cam rings formed of sections corresponding to the cam surfaces of the stator, and having projections fitting in the grooves in the interlor wall of said stator, a rotor turning within the stator, and comprising a hub portion and side members'carried thereby, and pistons sliding in grooves formed in the rotor.

2. In a rotary engine thecombination of a ring-like stator having an interior wall with eccentric cam-like surfaces, a rotor within the stator and steam spaces formed between the rotor and the stator, said stator having an inlet port leading to one of said steam spaces, an outlet leadin from the other steam spaces, and a channe connecting the two steam spades: interlocking packing rings corresponding in shape to the cam surfaces of the stator and arranged at the sldes of said surfaces, transversely disposed packing plates formed of sections, springs normally tensioned in the-packing plates, and sprin pressed pistons slidably mounted 1n .radia grooves in the rotor.

In testimony whereof, I afiix my signature, 1n presence of.two wltnesses.
